HAY-DERIRICK.

SPECIFICATION forming part of Letters Patent No. 727,104, dated. May 5, 1903.

Application filed December 20, 1902.' Serial No. 136,027. (No model.)

To all whom it may concern: i

Be it known that I, THOMAS DE LA MARE, a citizen of the United States, residing at Tooele, in the county of Tooele and State of Utah, have invented a new and useful Hay- Derrick, of which the following is a specification.

This invention relates to that class of devices known as hay-derricks and which are used for the purpose of unloading hay from a wagon and piling or stacking the same" where desired, said device being used in connection with an ordinary hay fork, sling, or.

grapple. Y

My invention has Vfor its object to provide a device of this class which shall be simple in construction, stout and durable, so as to be capable of handling heavy loads with ease and celerity, the construction being also such as to enable a stack of large 'size to be built' when the size of the machine is taken into In the accompanying drawings, Figure 1 is a front elevation of a.v hay-,derrick constructed in accordance with the principles of my invention. Fig. 2 is a horizontal sectional view with dotted lines'indicating the reversed position of certain parts of the machine. lower portion of the machine. y sectional detail view,^on an enlarged scale, taken through the upperportionvof the mast and the adjacent part-of the jib or derrickarm. Fig. 5 isasectional -detailview taken on the line 5 5 in Fig. 1.

Corresponding parts in the several figures are indicated by similar characters of reference.

The base of my improved derrick is composed of the sills l 1, supporting the crosspieces 2 2, which latter are extended beyond one of the sills to form brackets 3 3. An ad- Y upright position.

Fig. 3 is a detail `side View of Vthe.- Fig. 4 is a ditional cross-brace 4 is-preferably arranged diagonally, as will b e bestseen in Fig. 2 of the drawings. This diagonal cross-piece'supports the mast 5, which may be mortised therein and which is additionally supported by means of oppositelydisposed vertical braces 66', connected at their upper ends by means of a bolt 7, extending transversely through the mast ,and provided at their lower vends, which are screw-threaded, with nuts 8,

which are tightened up against the under side ofthe cross-brace 4. By this construction the lower end of the mast is connected very rmly with the cross-brace 4, and it is also well adapted to receive the transverse hinge-bolt 9, which extends transversely be-v tween the vertical braces 6 and which is held in positionV detachably by means of a pin 10, engagingia slot 11 in the end of said hinge-bolt. l2 12 designate braces, the lower ends ofwhicharev bolted to the cross-pieces 2 and the upper ends of which are connected with Ythe mastuby means of a transverse bolt 14 14 are inclined braces, the lower ends of which are bolted to the cross -pieces 2 2 and to the front'silll, while theirupper ends embrace the mast and are connected in rear ofthe latter by means of a bolt 15. An .additional bolt 16 is curved and extends through the braces 14 and through the mast 5, which is thus sustained firmly and rigidly in an The upper end of the mast-is provided with a Vthimble or ferrule 17', theupper sideor face of which may be provided with an annular groove 18, forming a ball-race, in which may be Vplaced antifriction-balls 19 to reduce the friction between the said ferrule and the revolnble cap 20, The latter is provided on its lupper side with lugs or ears 21, receiving between theln a casting 22, which is mounted pivotally'between the lugs 21 by means of a bolt 23. The casting 22 is provided With'laterally-extending [langes 24, the upper faces of which are concaved to support the derrickarm or jib 25, which is ,bolted to or otherwise suitably connected with said lian ges. The said casting 22 is also provided with oppositely-extending ears or lugs 26, through which extend the lower ends of eyebolts 27, the upper ends of `which receive a bolt 28, extending transversely through a brace-rod 29, which is thus IOO firmly supported upon the derrick-arm and which serves to support the truss-rod 30, the ends of which are suitably connected with the ends of said derrick-arm. The latter is thus braced and enabled to support heavy loads.

The lower end of the derrick-arm is provided with straps 31, having perforations 32 for the reception of a pin or bolt 33, by means of which adjustable connection may be made with the hinged brace-rod 34, which is provided with a plurality of transverse perforations 35 for the reception of the connecting pin or bolt 33. The lower end of the brace 34 has a strap 36, which is connected, by means of a link 37, with the hinge-bolt 9, which latter is provided with an eye for the reception of the pivot-pin or pintle. The brace 34, it will thus be seen, is thus not merely hinged, but has a link connection with the hinge-bolt, whereby it is enabled to move freely and whereby the range of its movement is increased. The brace-rod 34 is provided with a latch 38, one end ot' which is secured to the under side of said brace, while its opposite end extends through a perforation therein and is connected with thelatch-rope 39. The latch member 38, which constitutes a springlatch, is adapted to engage a catch 40, which is bolted detachably to the braces 12 and 14 on either side of the machine, so that it may be moved from one side to the other. For convenience one of the catch members may be secured permanently to the braces at each side of the machine when desired.

The hoisting-rope 4l, carrying the hoisting element 42, which may be of any desired construction and which, as already stated, may be a sling, a fork, or of any description, has one end attached at 43 tothe upper end of the derrick-arm, passing from thence under the pulley44,snpporting the hoisting element, and over a plurality of suitably-arranged guide-pulleys 45 to the point at which the draft is attached. Suitably connected with the hoisting-rope, at any desired point thereof, is the latch-rope or trip-rope 39, which passes through suitable guides 46 to the latch, with which it is connected. It is obvious that the time of tripping the latch may be regulated by lengthening or shortening the trip-rope.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my invention will be readily understood. When a loaded wagon is driven up in front of the derrick, the hoisting element is engaged with the load, after which by applying power to the draft-rope the load connected with the hoisting element will be elevated until the trip-rope is rendered su fciently taut to trip the latch, when by continuing the draft the derrick-arm Will be swung to the position at which it shall be desired to drop the load, the dropping being effected by means of a triprope 50, leading from the hoisting element to a point within convenient reach of the operator. When the draft-team is backed, the draft-rope may be restored manually by pulling upon the trip-rope 50, and the derrick may also be inaniially restored until the latch is in engagement with the catch. By simply reversing the position of the hinge-bolt 9, as shown in dotted lines in Fig. 2, and transferring the catch member 40 to the opposite side of the machine the initial position of the derrick-bar may be reversed, as will be readily understood, and by providing suitably-disposed guide-pulleys for the draft-rope and the triprope the draft may be applied at the opposite side of the machine, thus rendering it unnecessary to swing the derrick through more thanvhalf the space that would otherwise be required. This is considered a great convenience and saving of time and labor.

In building the stack a quantity of the hay will be deposited upon the projecting ends or brackets 3 of the cross-pieces 2 of the frame. The latter is thereby sustained in position and prevented from tilting. The ends of the sills are preferably provided with perforations, through which stakes may be driven into the ground for the purpose of assisting in retaining the device in operative position.

My improved hay-derrick While simple in construction and capable of being erected at a moderate expense is capable of handling heavy loads in a very rapid and satisfactory manner, and its working capacity is greatly increased by the means which I have provided for reversing the initial position of the derrick-bar, whereby the distance required to be traveled by the hoisting-team is greatly reduced.

The general construction of the device has been designed with a view to strength and rigidity. Especially do I consider the means for bracing the mast and for mounting the derrickbar of no little importance. The casting that supports the derrick-bar also serves, by means of the eyebolts 27, engaging the truss-brace, to sustain the latter, and I am enabled by the general construction herein described to use lighter and less expensive material than would otherwise be required in order to resist the strain to which the device will in practice be subjected.

Vhile I have inthe foregoing described a simple and preferred form of my invention, I desire it to be understood that I do not limit myself to the precise structuraldetails herein set forth, but reserve the right to any changes and modifications which may be resorted to without departing from the spirit and scope of my invention.A
